• If diode conducts, voltage across resistor is V_s − V_D = 5 − 0.7 = 4.3 V.
• I_D = 4.3 V / 1 kΩ = 4.3 mA.
• Check: forward conduction valid; diode voltage = 0.7 V.

Problem Type 3: Zener Diode Regulator

Problem: A Zener diode (breakdown voltage (V_Z = 5.1V)) with a series resistor (R_S = 470\Omega) is connected to an unregulated supply (V_in = 12V). The load (R_L = 1k\Omega). Find the load voltage and Zener current. Diode circuit analysis involves determining whether a diode
